SOAP-SHAVING DEVICE.

Application filed May 27, 1905, Serial No. 262,617. Renewed April 22,1915.

To all whom it may concern Be it known that I, FREDERICK Eoo-E,a c1t1-zen of the United States, residing at Bridgeport, in the county ofFairficld and State of Connecticut, have invented certain new and usefulImprovements in Soap-Shaving l )evices; and I do hereby declare thefollowing to be a full, clear, and exact descrlptlon of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to soap dispensing machines, the object being toprovide a device which may be used as a toilet fixture in connectionwith wash basins for the purpose of supplying soap in such a form thatit may be readily and economically used, thus doing away with the use ofa cake of soap in the ordinary manner in the hands.

The object of my invention is to provide a machine of simple and compactconstruction for the purpose above specified, which shall supply soap insuch a form that it will readily dissolve and lather freely in thehands.

To accomplish these results I have provided a machine wherein the soapis shaved into thin narrow strips or ribbons by a suitable comminutingdevice provided with cutting teeth adapted to be operated against a cakeof soap positioned within a suitable receptacle.

This invention relates more particularly to the comminuting device orcutter, but other objects will be in part obvious and will in partappear hereinafter in connection with the description of the deviceshown in the accompanying drawings as an illustration of an operativeembodiment of my invention.

Similar numbers of reference denote like parts in the several views ofthe drawings.

Figure 1 is a central vertical section showing one embodiment of myinvention in an improved device with the parts in position for use. Fig.2 is a plan view with the cover and parts carried thereby removed. Fig.3 is a detail plan view of the cutter disk. Fig. 4 is a detail elevationof the cover and the parts carried thereby. Fig. 5 is a view similar toFig. 4 but looking in a direction at right angles thereto. Fig. 6 is abottom view of the pressure plate. Fig. 7 is a detail broken view of thecase and cover in detached condition showing particularly the meansprovided for securing the cover in position.

Specification of Letters Patent.

Serial No. 23,217.

A casing is shown at 1 which is open at its lower extremity andsupported by any suitable means, such as the arm 2 which extends throughthe casing 1 so as to provide a platform or ledge upon which thecomminuting device or cutter 7 may be supported. The arm 2 may besecured to the wall or to any suitable fixture convenient to a washbasin.

7 is a cutter disk having a central hub 4 which latter is seated withina recess in the upper surface of the arm 2 so that said disk will behorizontally disposed and will be supported by said arm. Extendingthrough this disk and hub is a short shaft 3 the lower end of whichprojects loosely through the arm 2 While the upper end is preferablyformed into a tenon 6, the object of which is to provide for a freerotary movement of said disk. This disk is provided with closed slots 8whose inner extremities are near the axis of the disk and also withintermediate slots 9 whose outer ends open into the periphery of thedisk and whose inner ends ex tend about halfway to the axial center ofthe disk. All these slots have a general radial disposition and in thesame relative edges of these slots 8, 9, are formed cutter teeth 10, 11,which teeth are bent upward slightly for the purpose presently to beexplained. The cutter disk revolves, as will be presently set forth, andits function is to shave the soap into very fine particles, andtherefore it will be clear that there is more or less strain upon thisdisk during the process of shaving the soap. Accordingly it will bemanifest that radially disposed slots out from the periphery to. a pointnear the axial center of the disk would so weaken the latter that itcould not withstand the strain of cutting ,the soap and thereforeparticular attention is called to the manner of forming these slots asabove described, so that the sweep of the cutting teeth will cover anarea of a diameter substantially equal to the diameter of the diskitself. When in operative position this cutter'is contained within thecasing near the bottom thereof and is supported by the upper surface ofthe arm 2.

Secured to the interior of the casing is a vertically disposed fin 12which extends from a point near the top of the casing down to a plane aslight distance above the cutter disk. The soap cake a itself has acylindrical shape, is adapted to fit snugly within the casing, and has avertical groove 13 in the side into which this fin extends when the soapis placed within the casing, so that it will be clear that the soap isincapable of rotary movement. The soap is placed in position within thecasing and rests immediately upon the cutter disk 7, the teeth of thelatter extending upwardly so as to be capable of scoring or cutting thesoap when said disk is revolved. It therefore is necessary to providemeans for revolving the cutter disk and at the same time to hold thesoap firmly against said disk, which part of my invention I will nowdescribe.

The soap itself is made with a central opening 14 extending from top tobottom and when this soap is in position on the cutter disk the upperend of the short shaft 3 will project upwardly within this opening.

15 is the cover of the casing which cover is provided with teats 16, atdiametrically opposite points, adapted to engage with verticallydisposed channels 17 in the top of the casing and by a slight turn ofsaid cover adapted to be thrust within deflected portions 18 of thesechannels, whereby the cover and casing may be detachably securedtogether in a very well known and ordinary manner.

19 is a shaft secured to the top of the cover in any ordinary manner soas to be capable of free revolution, and to the outer extremity of thisshaft beyond the cover is secured a crank 20. The lower extremity ofthis shaft is formed into a head 21 capable of passing freely throughthe opening 14 in the soap, said head being mortised as shown at 22 soas to engage snugly with the upper end of the shaft 3 and its tenon 6whereby the cutter disk may be revolved by turning the crank 20.

To hold the soap against the cutter I prefer to employ a disk 23 havingserrations 24 depending from the bottom face which disk rests directlyupon the soap and has secured to its upper face concentrically therewitha hollow thimble 25 and is cut out at the center so that the head 21 ofthe shaft may pass through the disk 23 Within said thimble, said shaftextending loosely through the top of the thimble.

26 are levers which are pivoted together at 27 at their centralportions, and 28, 29, are short levers whose outer ends are respectivelypivoted to the outer extremities of the levers 26, the inner ends ofthese short levers being respectively pivoted together and also to astationary collar 30 secured to the underside of the cover and to thehollow thimble 25. There are two sets of these levers pivoted in themanner described on opposite sides of the shaft 19, and I employ coilsprings 31 whose extremities are secured to the pivotal points at theouter extremities of each of the two sets of short levers 28, thefunction of these springs being normally to draw together the ends ofthe levers. These levers are therefore arranged after the manner of lazytongs, and the serrated disk 23 will accordingly be con stantly forcedagainst the cake of soap and the pressure will be uniform. The serrateddisk 23 is secured as against turning by means of a notch 32 in theperiphery of said disk which engages with the fin 12.

The parts being in the position as shown at Fig. 1, the revolution ofthe crank 20 will cause the cutter disk to shave very fine particlesfrom the bottom of the cake of soap which particles will be dischargedfrom the bottom of the easing into the hand of the person using thedevice. When the disk 23 is at its lowermost position within the casingwith the levers 26, 28, and 29 fully extended, said disk will just clearthe upwardly projecting teeth of the cutter disk, and when the soap cakehas been reduced so that it is very thin the serrations 24 willcooperate with the cutter teeth to completely grind up this remnant ofsoap so that it may be discharged from the casing.

In renewing the soap, the cover and the parts carried therebv areremoved from the casing and after a fresh cake of soap has been placedwithin such casing the cover is placed in position and is depresseduntil the head 21 engages with the shaft 3 and tongue 6, the cover beingthen looked to the casing in the manner hereinbefore described.

The arm 2 affords a ledge or platform within the casing for the supportof the various parts of my improvement, but of course any suitable ledgeor equivalent may be provided within the casing and the arm may besecured to the outside of the casing, and various other changes may bemadethat are simple and within the range of ordinary mechanical skill,all without departing from the spirit of my invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. A cutter adapted for use in a soapdispensing machine, comprised of a circular disk having a series ofrectangular openings closed at both ends and whose inner extremities arenear the axis of the disk and also having a series of rectangularopenings whose outer ends open into the periphery of the disk, saidslots being provided with integral serrated cutting edges on one sidethereof.

2. A cutter adapted for use in a soap dispensing machine, comprised of acircular disk having a series of rectangular openings closed at bothends and whose inner extremities are near the axis of the diskandextending to a point intermediate the center and the peripherythereof and also having a series of rectangular openings whose outerends open into the periphery of the disk and extending substantiallyhalf way to the center thereof, said slots being provided with integralserrated cutting edges on one side thereof.

3. A cutter adapted for use in a soap dispensing machine, comprised of acircular disk having a series of rectangular openings closed at bothends and whose inner extremities are near the axis of the disk andextending to a point intermediate the center and the periphery thereofand also having a series of rectangular openings alternately positionedwith said first series of openings and whose outer ends open into theperiphery of the disk and extending substantially half way to the centerthereof, said slots being provided with integral serrated cutting edgeson one side thereof.

4. A cutter adapted for use in a soap dispensing machine, comprised of acircular disk having a series of rectangular openings closed at bothends and whose inner extremities are near the axis of the disk andextending to a point intermediate the center and the periphery thereofand also having a series of rectangular openings whose outer ends openinto the periphery of the disk and extending substantially half way tothe center thereof, said slots being positioned with one edge extendingradially and said edge formed with integral serrated cutting edgesprojecting above the surface of said disk.

In testimony whereof I affix my signature in presence of two witnesses.
